Title: Manufacture of non-volatile semiconductor storage device
Inventor: KAWADA MASAHITO
IPC: H01L21/8247
Filed: 1998-12-10
Abstract: PROBLEM TO BE SOLVED: To provide a method of manufacturing a flash memory comprising a low-voltage transistor having a sufficient element isolation characteristics. SOLUTION: Related to a method for manufacturing a flash memory, a low-voltage transistor part constituting a peripheral circuit goes through many etching processes, so an isolation oxide film 101a in that region is eroded for degraded isolation characteristics. To prevent this, a resist mask 103 is used to allow the isolation oxide film 101a to remain. Further, at etching of a composite film 107b of a high breakdown-strength transistor part, a resist mask 108 is used to prevent etching of a composite film 107a of the low-voltage transistor part.
